Elevated tree mortality and reduced recruitment of new trees linked to drought and fires has been reported across a range of forests over the last few decades. Forests that resprout new foliage epicormically from buds beneath the bark are considered highly resilient to disturbance, but are potentially at risk of elevated mortality, demographic shifts and changes to species composition due to synergistic effects of drought and fire. Despite this, the effects of drought-fire interactions on such forests remain largely unknown. We assessed the effects of drought severity and fire frequency on juv...

Avatar that suits them. d.j. soto started the church in 2016. he calls it faith filled. >> when people see me preaching, they'll see my hand gestures, head movements and hand gestures. it's really not that different from a physical church experience. >> reporter: the pandemic changed the way people worship. the virtual church ushered in a whole new way of connecting to god. >> we're talking about moses and the red sea. not just talking about it on stage but we're walking through it as we look up, the water is coming down. we'll go up to the burning bush. there's animated fire effects. people w...

Increases in tree mortality linked to drought and fires have been reported across a range of forests globally over the last few decades. Forests that resprout epicormically/aerially should be the most resistant and resilient to changes in fire regime, yet they may be at risk of increased mortality, demographic shifts and changes to species composition due to the compounding effects of drought and fire. Despite this, the synergistic effects of drought and fire frequency on resprouters has received less attention than for obligate seeder tree species. Our study examined the effects of drought se...

California, home of the freeway and the car-based lifestyle, has long struggled with air pollution — and been a pioneer in cleaning up the air, for example in vehicle emission standards. But in recent years, a new threat to air quality has emerged as summer and fall bring some of the worst wildfires in state history, spreading smoke and haze over hundreds of miles. “I didn’t anticipate it, and I don’t see an end to it,” said professor Anthony Wexler, director of the UC Davis Air Quality Research Center, who has studied air quality issues for over 30 years. UCCalifornia, home of the f...
